Filed Jan. 15, 1959, Ser. No. 787,034 19Claims. (Ci. 12-122) Thisinvention relates to apparatus, for operating on the ends of shoes, ofthe kind disclosed in a pending application for United States patent,Serial No. 778,188, filed December 4, 1958, in the names of Robert B.Dunlap and Jacob S. Kamborian, now Patent No. 3,011,186, grantedDecember 5, 1961, and, in particular, to mechanism adapted to beemployed in conjunction with that machine for setting staples orequivalent attaching elements through the margin of the upper after ithas been stressed inwardly over the shoulder of the last into engagementwith the insole rib and optionally to trim the excess margin. It is tobe understood, however, that the mechanism could be used in conjunctionwith any end lasting machine where there are wipers or equivalent meansmovable about the end of a last operable by such movement to stretch themargin inwardly over the shoulder of the last, into engagement with theinsole rib.

The principal objects of the invention are to provide improved stapledriving mechanism for use in conjunction with the aforesaid machine inwhich the staples will be driven into the insole rib substantiallyperpendicular to the curvature thereof at the point of drivingregardless of the angular position of the wipers; to provide stapledriving mechanism which will set the staple through the margin and ribclose to the base of the latter; to provide staple driving mechanismwhich can be put into operation, or not, so that the machine mayoptionally be used as disclosed in the aforesaid application for cementlasting or welt lasting; to provide staple driving mechanism which is ofrelatively simple design and can be incorporated in a conventional toelasting machine without impairing its use for cement lasting; and toprovide staple driving mechanism for automatically setting the stapleswhen the wipers become engaged with the insole rib. Further objects areto provide manually operable staple setting mechanism in conjunctionwith the automatically operable staple driving means optionally useableindependently of the automatic driving means for setting additionalstaples between the previously driven staples and the pulling overtacks. Further objects are to provide means for trimming the excessmargin simultaneously with the fastening operation or following thelatter.

As herein illustrated, the machine has means for mounting a last, uponwhich the upper and insole are assembled, means angularly movable abouta point on a median line of the last to close about the ends thereof,means for effecting relative movement of the last and members relativeto each other to bring the members into engagement with the upper at thebase of the insole rib, and staple driving means carried by the membersoperable when they engage the margin at the base of the rib to drivestaples through the margin into the rib. The aforesaid members arewipers, have concave leading edges and are angularly movable so as toconform to the shape of the toe and the driving mechanism is so disposedon the Wipers as to drive the staples through the leading edges of thewipers in a plane parallel to the bottom of the last, substantiallyperpendicular to the curvature of the insole rib at their point ofengagement therewith, so as to set the staples close to the base of therib. There is means for effecting driving movement of the drivers of therespective wipers regardless of the angular disposition and means forsupplying staples, one at a time,

to each driver for each driving operation. One or more drivingmechanisms may be associated with each wiper for driving one or morestaples into the toe at each side of the tip. For trimming, knives aremounted on the wipers or carriers substituted therefor and the meansmounting the last includes a jaw having engagement with the insole andparts, one of which engages the inner side of the rib and the other ofwhich projects forwardly above the. rib and cooperates with the knivesto shear the margin.

The invention will now be described in greater detail with reference tothe accompanying drawings wherein:

FIG. 9 is a fragmentary section showing the trimmer in operation; and

FIG. 10 is an elevation of one element of the clamps showing thestarting switch forinitiating operation of the machine when the. shoe ismounted in readiness to be operated upon, taken on the line 10-10 ofFIG. 7.

Referring to FIG. 4, there is shown in dot and dash lines a frame 10which supports a pair of toe clamps12 and 14, a heel clamp 16 and a pairof wipers 13 for movement relative to each other to stress an upperheightwise of the last and inwardly over the bottom.

The wipers 18-18 (FIG. 1) are fastened respectively in a pair of camplates 29-20 supported on a slide plate 22 for bodily movementtowa-rdthe end of the last and for g m nt on the slide plate. to close thewipers about the end of the last, The angular movement is eifected bymeans of curved cam slots 24-24 and links 26-26 and the linear movementis effected by levers 28-28. The links and levers 26-26 and 28-28 areconnected to a head 30 slidable in a slot in the plate 22, the head inturn being fastened to the end of a piston rod 32 protruding from afluid pressure operated cylinder 34. The details of the constructionand. operation of the aforesaid mechanism are clearly set forth in theaforesaid pending application for patent and since they do not inthemselves contribute to the staple driving except to advance the wipersinto position for the driving operation they will not be describedfurther herein.

Each of the Wiper blades 18 (FIGS. 2, 3 and 3a) contains a narrowelongate T-shaped slot 36 disposed at such an angle that the mouth ofthe slot opens through the leading edge of the wiper blade substantiallyat right angles to the curvature of the leading edge at that point. AT-shaped driving member 33 (FIG. 3a) is arranged to slide in the slot 36and has fastened to its underside a pin 40 which is engaged with an,arcuate groove 42 formed in a block 44 situated beneath the wipers(FIG. 3). The block 44 is fastened to a-post 46 (FIG. 4), at the forwardend of a slide bar 48, which is disposed in a horizontal guide passage50 so that the block 44 is constrained to move horizontally along themedian line lengthwise of the last. The lower end of the post 46 ispivotally connected at 52 to a driving arm 54, which in turn ispivotally connected at its lower end to one endof a link 56, theopposite end of which is pivotally connected to the frame of themachine. The forward end of a piston rod 58 is pivotally connected tothe driving arm 54 intermediate its ends and motion is imparted to thepiston rod by a fluid pressure operated cylinder 60 which is pivotallyconnected at its rear end to the frame of the machine. By admitting apressure fluid to the cylinder 60 the driving arm 54 may be movedforwardly and rearwardly so as to impart corresponding movement to theblock 44. Forward movement of the block 44 will impart movement to thepins 40 and hence to the driving members 38.

The arcu-ate groove 42 in the block 44 permits the maintenance of adriving connection between the driving arm 54 and the staple drivingmembers 38 regardless of the angular position of the Wipers, for as thewipers are closed about the end of the shoe the pins 40 slide within thearcuate slot 42 so that they are always in alignment with thelongitudinal axis of the drivers and so that movement of the block 44forwardly imparts movement to the drivers through the pins at theparticular angle at which theyhappen to be disposed at any given time.There is enough play in the linkage consisting of the driving arm 54 andmember 56 by reason of their pivotal connections to permit the 'block tomove forward linearly as the wipers are advanced toward the end of thelast to take up the distance between the leading edges and the last.Staples s are supplied to the driving members 38 through slots 62 (FIGS.2 and 3) in the wiper blades which have communication with the passages36 and vertically disposed staple magazines 64 fastened to the wipersfor movement therewith by screws'66. Each magazine is adapted to receivea stick of lightly attache-d staples 6'8, such as are conventionallyavailable for staple driving devices and the stick is pressed downwardlyinto the magazine 'by a follower 70 backed by a spring 72. As thedriving member 38 moves forwardly it detaches the lowermost staple fromthe stick and drives it into the work. When it returns the next stapledescends into the passage in readiness for the next forward movement ofthe driving member. During the forward movement of the driving members,the pins 40 slide in the slot 42 toward the lengthwise median line ofthe last.

As will be seen by reference to FIG. 3, since the wiper itself hugs thebottom of the shoe very closely the mouth of the staple passage is closeto the base of the inseam rib r and hence the staple is driven close tothe base. 7 To insure clinching of the staple the jaw 12 is shaped sothat its edge engages the inner side of the inseam rib r (FIG. 3) andmay, if desired, have a concave surface 74 for assisting in turning thelegs of the stapleinwardly.

I As shown in FIG. 2, there are two staple driving mechanisms, oneassociated with each wiper blade, and for most purposes a single stapledriven into the lasting margin through the rib, one at each side of thetip, sufiices to hold the upper taut without need for a lasting wire oradditional fastening means until the welt can be attached. If the uppermaterial is very thin and hence has no body for holding its shape or isheavy and stubborn to shaping it may be desirable to insertadditional'staples between those inserted at either side of the toe andthe pulling over tacks t shown in FIG. 6. This maybe done by employingadditional staple driving mechanism, shown in dotted lines in FIG. 5,identical with that described above, to be operated automatically asheretofore explained to drive two more staples, one at each side of thetip, so that there are two staples at each side betwen the tip and thepulling over tacks.

Very good results can be obtained with only two staples, one on eitherside of the toe when the upper itself is impregnated with aquick-setting thermosetting resin. By using a resin which sets upquickly sufiicient stifiness is imparted to the upper so that inconjunction with the two staples substantially none of the tautnessimparted to the upper by the lasting operation will be lost. Similarresults may be obtained by using a box toe impregnated with aquick-setting thermosetting resin.

Fluid pressure is supplied to the cylinder 60 by appropriate valves andvalve operating solenoids when the wipers reach the innermost extent oftheir wiping movement and are engaged with the insole rib. This mayconveniently'be affected by a switch added to the timer T of theaforesaid toe lasting machine which supplies current to the coil of asolenoid operated valve to supply the pressure fluid to the cylinder, atone end to advance the driving member and at the opposite end to retractit.

As heretofore described, the stapling means is shown in combination withwiping means and it is customary to remove the shoe from the machineafter the upper is wiped inwardly against the rib and stapled theretoand place it in a trimming machine for removing the excess marginalmaterial. It is a further object of this invention to add a trimmer tothe wipers so that trimming can be accomplished simultaneously with thewiping and stapling operation without transfer to another machine. Thismay be done by fastening a trimming blade to each of the wiper blades soas to be movable therewith, or by removing the wipers and substitutingtherefor trimmer carrying supports which operate to impart wiping actionto the margin as trimming is effected. It is within the scope of theinvention, however, to combine trimming and stapling in a machineindependently of the wiping and to transfer the shoe from the machinedescribed above, in which the margin is wiped over and two staples areinserted at the toe, to a machine in which the margin is trimmed andadditional staples are inserted.

More specifically, as shown in FIGS. 7 to 10 inclusive, there is shown apair of carrier plates 82-82 which may be bolted to the cam plates2tl20, shown in FIG. 1, so as to be movable about the end of the shoe.At the forward upper edge of the plates"82-82 there are fastenedtrimming knives 8484, preferably so as to be readily removable forreplacement as they become dull. To effect trimming the clamp '12, shownin FIG. 4, is replaced by a clamp 12a, containing a groove 86 in itsedge face, a forwardly extending lip '88 at the top side of the grooveand a forwardly extending lip 99 at the bottom side of the groove.

As shown in FIG. 8, when the last is held clamped between the clampingmembers 12a and 14, the lip 90 bears against the inside of the insolerib r and the lip 88 projects over the upper edgeof the rib. Theundersurface of the lip 88 lies substantially in the plane of the uppersurface of the knives 8484 and forms a shearing surface, the lip 88holding the marginal material of the upper upright so that it can besheared off by the forward movement of the knives 8484. The groove 86provides a space for movement of the knives inwardly beyond the edge ofthe lip 88.

As previously described in detail, with reference to the wipers 18, eachcarrier 82 contains passages 92 for staples. A driver 94 is arranged toslide in the passage for driving staples supplied thereto through theforward end of the carrier and through the margin and insole rib againstthe clamp 12a. The rear ends of the drivers, of which there are two, asshown herein, are provided with pins 96 which engage an arcuate groove98 in a block 164 which corresponds to the block 44 previouslydescribed. The staples S are supplied to the passages 92 at theundersides of the carriers 8282 from magazines 102-402,, asdistinguished from the upper side. The lip 90 contains recesses 104 forturning the legs of the staples as they are driven through the rib intoengagement with it.

As thus constructed, it is clear that as the members 82-82. moveinwardly over the shoulder of the last their undersides impart an inwardwiping action onthe upper, forcing it into the corner between the upperside of the insole and the insole rib, substantially simultaneously withthe cutting operation which severs the excess margin and that as thecutting is completed the forward edges of the carriers 8232 force theupper into the corner at the base of the rib. At this point the staplesS are driven as shown in FIG. 9.

When the trimming means is added to the end lasting and stapling machinedescribed above, operation of the machine is initiated in the usualmanner by push button vcontrol. If the trimming means is embodied in anend lasting and stapling machine independently of the aforesaid endlasting machine operation may be initiated by a microswitch 105 mountedin the clamp 12a, with its trip 1% aligned with a pin slidable in apassage in the clamp, with its forward end projecting slightly beyondthe lip 9%. Thus, when the last, with the upper assembled thereon, isplaced between the clamps and pulled up into position to be operatedupon, the insole rib r pushes the pin 108 rearwardly, thus actuating thetrip of the switch element 106.

It should be understood that the present disclosure is for the purposeof illustration only and that this invention includes all modificationsand equivalents which fall within the scope of the appended claims.
